基于安卓智能手机的GNSS单点定位精度分析
Accuracy analysis of GNSS single point positioning based on android smartphones
摘要
Abstract
Smartphones integrated with Global Navigation Satellite Systems(GNSS)serve as the primary devices for obtaining spatial location in human daily activities,with Single Point Positioning(SPP)being the core technology for real-time GNSS navigation and positioning on these devices.However,the research remains incomplete regarding the SPP performance of the current generation of Android smartphones supporting multi-GNSS in various scenarios,which leads to uncertainties in the optimal selection of satellite systems.Taking the real-time SPP positioning of an Android-based Huawei smartphone as a case study,this paper analyzes GNSS observation quality and positioning performance under different conditions and positioning modes,comparing the results with those of traditional geodetic-grade GNSS receivers.The results indicate that in a static SPP mode,the combination of GPS+BDS yields superior positioning accuracy in open and semi-obstructed environments with favorable observation conditions.In a dynamic SPP mode,when a sufficient number of GPS satellites are available,selecting GPS alone for smartphone SPP positioning is recommended.In cases when the number of GPS satellites is limited,the GPS+BDS combination proves to be the least affected by observation conditions,effectively meeting the majority of users'daily require-ments.关键词
